to have ads like this. I typed-up a reply to a question that was posed and after scrolling up to ensure that I had addressed all of the OP's concerns an ad for cat-litter covered my response and would not close nor allow me to post the response.

It is incredibly frustrating to take the time to answer someone's question then have it rendered unusable by a cat-litter ad.

Furthermore, why is it that I have to turn my sound off to look at this forum so that I don't have to hear about cat-litter?

I am NOT tired of "heavy cat-litter"!! I don't have a cat! (Good thing too as I am sure one of the dogs would have eaten it by now)
